To all whom it may concern:

Be it known that I, Tanoor C. Dnx'rrn, a citizen of the United States, and residing at Pearl River, in the county of Rockland and l State of New York, have invented certain new and useful Improvements in Sheet-Registering Mechanism for Paper-FeedmgMachines, of which the following is a specification.

The recent developments in printing mal chinery have necessitated eater rapidity in the operation of automatic paper feeding machines and at the same time the accurate 3 registry of the sheets fed to the press. Tlns i is true with particular reference to the offset I press, which is most usually designed for the rapid printing of relatively small sheets. In the operation of this ofl'set printing press, a sheet must be fed to the press for each revolution of the impression cylinder, and since the length of sheets to be printed is frequently but little less than the circumference of the impression cylinder and the press is run at a very high speed, itnaturally follows that but little time is aiforded for the registry of the sheets at the gages of the press. For instance in some cases to which my attention has been directed, the sheet to be printed is only nine or ten inches shorter than the circumference of the impression i cylinder which is o eratcd at a speed of from 3,000 to 5,000 s eets per hour. In this particular instance, there was not suflicient time between the arrest of the sheet at the press gages and the action of the cylinder grippers in taking a. sheet to side register the sheet more than 9.,- or i of an inch, even with a very rapidly operating sidc registering mechanism.

The difficulty in presenting sheets rapidly and accurately to this type of printing press is solved by the present invention. which consists hroadty in. providing upon a conveycr frame arranged between an automatic two sheet registering mechanisms. arranged to act successively upon the sheets. the first one of which serves to effect a preliminary 1 registry or lateral positioning of the sheet while it is rapidly advancing upon the cou veyer for the purpose of placing the sheet suliiciently near its final registered position at the gages to enable the second registering l per roller to cause it registering it and release the sheet after it is registered. 1 nism, it will he observed that while the short mechanism to accurately complete the regstering operation, and the second registermg mechanism operates upon the sheet at the gages to place it in exact registry posltion.

In the preferred embodiment of my present invention, I provide the usual form of sheet conveyor with a preliminary side registerin flange or plate arranged parallel with tie direction of travel of the sheets at the leading end of the conveyor, and a plurality of twisted tapes extending a portion of the length of the conveyor so as to have a side registering tendency to place the registering edge of the sheet against said registering plate or flange while the sheet is rapidly moving from the fcedin machine to the press gages; and at the delivery end of 5 the conveyor frame I provide a rapidly actmg sheet registering device comprising 2 preferably a side registering and coiiperating rcgistc age or face ro lcrs between which the sheets are passe and an operating mechanism for rotating said rollers and for intermittently moving them into and out of peripheral engagement with a sheet to cause them to quickly engage a sheet Eaud shift it laterally into final registered 5 position immediately after ithas touched the front gages of the press, and then release itin its registered position just prior to the elevation of the press gages and the closing of the cylinder grippers- In this preferred en'lhodiment of my invention, the

final registering rollers include a constantly driven smooth-surfaced metal roller arrzmgcd beneath the plane of feed of the sheets, a cooperating frictionally driven rubber-faced upper roller mounted upon a morable support or frame. and a rotary cam for intermittently raising and lowering said upto engage a sheet for With this improved mechais rapidly advancing upon the shout convcyer, it is automuticalh' shiftcd laterally upon the com-"cycluntil lts registering cdgv is in contact with the preliminary registering plate or flange, which.

frame as to place the sheetwithin a fractioual distance of its final side registered po it will ho. uudcrstood. is so positioned upon tlu conveyor gested, but

' sition, the final registering device being so positioned that it will engage the sheet at. f thecstrenie edge and impart to it its final fside registering movement.

lhe employmentof cooperating upper and lower 1' istering rollers has been sug- Ee luck of success in the past with this form of registering device has been due mainly, if not entirely, to the fact I that the necessity of locating the registering L rollers far enough away from the registering gage or face to insure their engagement with the sheets under the wide range of variations of the successive sheets which are operated upon, causes these rollers to somei times engage the sheet so far from the registering gage that the action of the rolleis in registering the sheet (particularly when acting upon thin paper) will crnmple or i bend the sheet between the gage and the rollers, thereby destroying the registry. This difiiculty has been partially overcome by providing automatic trips for such registerin rollers, but such automatic trips are tion of my improved mechanism, I am able, by the action of the preliminary registering 5 device, to place the successive sheets so accurately that the final registering device is notrequired to move the sheets over 1; of an inch, which is of the greatest importance not only in the interest of accuracy, but because of the rapidity of action that is required.

In order that my invention may be fully emcee ri e, and l 'igs. 4 null R are respectively a dcl'uil plan and detail side elevation of the rekul'rllillc mechanism for causing the final registering mechanism to recede from the edge of the sheet after the sheet is registered.

Referring first to Figs. 1- and 2 of the drawings, 1 represents a part of the frame of a printing press, 2- a mart of the impressic-n cylinder thereof, 3 tie press gages, and 4 part of the frame of an automatic :1 )er feeding nmchine, which press and ee er frames are usually rigidly connected by tic bars, such as shown at 5. The automatic feeding machine may be of any suitable construction since it forms no part of my present invention. The drawings show the under feed shaft 6 of the feeder drop-roller delivery mechanism and the main cam shaft 10 from which all the parts of the feeding machine are usually driven.

The conveyer frame proper comprises suit able longitudinal side bars 15 connected at their ends with corner brackets 16 and 17. The usual transverse tie rods and shafts extend between the side frames and brackets. The brackets 16 are pivotally mounted upon studs upon brackets 32 for pivotally connecting the conveyer-to the frame of the paper feeding machine.

Journaled in depending lugs of the forward brackets 17 of the conveyer frame is the idler tape roller 20. The forward detachable section 26 of the conveyer frame is designed to restupon the press frame 1 and is formed with open sockets 25 in which fit studs 27 projecting laterally from brackets 17, as shown particularly in Fig. 1. This fin-ward section '26 of the conveyer frame supports the final side registerin mechanism hereinafter referred to, and ilie under guide slats upon which the forward part of understood, I will first describe the same f with reference to the accompanying drawmore particularly in the annexed claims.

In said drawings: Figure 1 is a side elevation of a sheet conveying mechanism having my improvements applied thereto. Fig. I is a detail cross section of the preliminary resistering plate or flange. Fig. 2 is a detail plan view of a part of the mechanism shown in Fig. 1. Fig. 3 is an enlar (1 detail vertical longitudinal sections view the sheet rests when in engagement with the press gages 3.

30 is the tape drum jonrnaled in the forwardly projecting brackets 32 of the paper feeding machine. This drum 30 supports and drives the main conveyor tapes 35 which pass around said drum and around the idler lugs, and afterward point out the novelty showing an outside elevation of the final a registering devite. Fig. 4 is a detail plan view of the final registering device. Fig. 5 is a vertical transverse sectional view showin another elevation of this device. Fig.

6 1s a detail sectional view illustrating the controlling cam for the final registering deroller :20, a series of usual idler pulleys 36 engaging the under lap of the belts for holding them taut. The tape drum 30 is driven from the shaft 6 of the feeding machine through the gears 40. 41 and 42. A gear 45 keyed to the )rojecting end of the shaft of drum 30 meshes with and drives an intermediate gear 46 which in turn meshes with a gear 47 formed integral with the hub 48 of bevel gear 49 'ournaled upon a stud of bracket 32. The have] gear 49 meshes with 1 and drives a similar bevel gear 50 keyed to the rear end of a shaft- 51 which extends longitudinally (If-tile conveyor frame and is journaled in bracket arms 52. This shaft 51 is for the purpose of driving an improved slowdown mechanism which forms no part of my present invention, but which is the subject, of an application filed by me the 25th day of August, 1909, Serial N 0. 514,602.

60 is an idler tape roller extending transversely of the conveyor frame approximately midway between its ends and sultably ]0l11'- naled in the bracket arms 61 secured to the side bars 15 of the conveyor frame.

65 represents a series of short endless conveyer tapes assiu around the tape drum 30 and the i ler roller 60, and having their conveying surfaces arranged approximately in the same plane as, and between, main conreveltapes 35. These tapes 65 are twisted as represented in Fig. '2 for the purpose of having a worm action upon the sheets as they are conveyed forwardly by the main conveyor tapes to move the sheets laterally upon the conveyer frame by then travel for wardly.

Projecting inwardly from brackets of the conveyor frame are the rigid rods or bars '71 upon which is adjustably mounted the preliminary registering plate or blade which extends longitudina 1y of the conveyer frame and limits the lateral movement of the sheet acted upon by the twisted tapes 65. The late or blade 75 is preferably of angular s tape in cross section as showp in ig. 1 to etfectively confine the register ed e of the sheet. This registering plate orgilade 75 extends approximately one-half the length of the conveyer frame, it bei necessary that the sheet he bevond and free from 881d registering plate when it reaches the front gages of the final registering mechanism to act.

W'hile I have shown in the drawings only one registering blade 75, it will of course be understood that I nfay arrange such a blade upon opposite sides of the conveyor frame, or at least provide two sets of supporting arms 71 to facilitate the transfer of flllS registering blade from one side of the conveyer to the other. When the registering blade is moved to the opposite so? of the come er. it will of course be understood that t e twisted tapes must be twisted in a reverse direction to shift the sheet laterally to the opposite side. I prefer, however, to always maintain the registering blade 75 on the same side of the conveyor frame for efi'ecting the preliminary ositioning of the sheet, no matter which sir e of the machine the final registering mechanism is operating upon, it being clear that even when the final registering mechanism is on the side of the conveyor frame opposite to the preliminary registering blade 75, the sheet can be given about as accurate a preliminary position although adjusted with relation to the edge which is opposite the final side registry edge. The action of the twisted tapes in combination with the longitudinally extending registering blade is to give the successive sheet-s the press so as to permit moving through the conveyor a preliminary positioning or registry upon the conveyor so as to leave the smallest possible registering movement for the action of the final registerin device.

lhe forward portion 26 'of the conveyor frame is formed with bearin for the reception of a laterally extendlng reciprocatory flat bar upon which the final side. registering device is adjustably mounted. S5 is the bottom plate of this final side registering mechanism provided upon its under surface with the yoke 86 which embraces the tmnsversc bar 80. The rear end of the plate has a downwardly inclined lip 85' which is presented just in front of the idler ta c ml or 20 for the purpose of guiding tie leading edge of an advancin sheet into proper relation with the fin.- registering device.

is the under side registering roller, preferably of smooth-faced metal mounted upon a short shaft- 101 extending parallel with the travel of the sheets and jolu-naled in bearings 102 projecting beneath the plate 85. This under roller is mounted with its upper periphery in the plane of feed. The shaft of this lower roller 100 has keyed to it the small worm gear 101* meshi with a similar worm gear 103 keyed to the ower end of a short vertical shaft 104 suitably journaled in an upright bracket arm or hearing 105. This bracket arm 105 projects from a plate 106 secured to the bottom plate 85 by means of bolts 107. The upper end of the vertical shaft 104 has keyed to it a worm gear 110 meshing with a similar worm gear 111 carried by the end of a shortshaft 112 freely journaled in the bracket 113 supported upon the plate 106. This shaft 112 is formed with a socketed end at 112 to receive a short shaft section 115 of a universal joint coupling 116 of a driving shaft 117. A set screw 118 secures the coupling shaft section 115 in the socket of short shaft 112.

120 is an inwardly and rearwardly projecting curved guide plate-mounted upon the bracket arm 113 to assist in guiding the leading edge of the sheet at the registry side into position with relation to the final registry device.

Shaft 112 carries a cam 12:) havin" a low portion Arranged between the cam 125 and one of the bracket bearings 113 is a vertically movable frame having in its vertical arm an elongatul slot 131 through which the shaft 112 extends, said slotpermitting the frame 130 to he moved freely upwardly and downwardly. An anti-friction roller 132 is jonrnaled at 133 in the upper end of frame 130 and runs in periph eral contact with the cam 125 by which the frame 130 is operated. The lower end of the frame 130 is of yoke-shape to receive the upper rubber-faced registering roller [-10,

which is mounted upon at short shaft 141 freelyjournalecl iuthe two arms 184 and "-135 :Df the 'oke-shapcd lower end of frame 5130. The rame 130 supports the roller 140 in the same vertical transverse plane as the lower roller 100 and in peripheral contact therewith (or with the sheet between them) when roller 14A) is in lowered fposition. The lower oke-shaped portion frame 130 is form .with two sheet guiding arms or shoes 13% and 135* whic1 are presented parallel with the upper face of the plate 85 and have upwardly turned inner ends. When this frame, carrying roller 140, is in lowered position, the guide fingers or shoes 134i and 135 are presented very close to the surface of plate 85 upon opposite sides of the roller 1&0, so as to effectively confine the sheet within close limits at the point of registry.

Projecting upwardly from the yoke portion of frame 130 is a lug 145 to which is pivoted at 146 a lever 1&7 journalecl to the vertical bracket arm 105 at 1 18. A sprin actuated rod 150 is pivoted to the outer en of lever 147 at 151 and passes freely through a guide lug 152 and supports an expansion spring 153 which is confined upon the rod 150 between the lug 152 and an adjustable collar 154 upon said rod. The purpose of the sprin 153 acting upon lever 1&7 as just explain is to press t e rubber-faced registerin roller 140 against the lower positively riven roller 100 and to cause the antifriction roller 132 to follow the controlling cam 125 in the registerin operation.

The shaft 117 may be riven in any suitable manner, and as shown in the drawings is driven through a universal joint couplin 160 with a short forwardly projecting shaf t 1(11 journaled in a bracket 16:2 hung from cam shaft and having worm gear con nection 163-164 with said cam shaft. It will be observed from Figs. 1 and 2 of the drawings that the drivin" shaft 117 is extended from the center of the cam shaft 10 to the side of the conveyor frame whereit is con led with the final registering device. The slaft connection being removable, itwill be understood that a final registering device at either side of the conveyer may be coupled up and operated. ith driving connection for shaft 117 geared to the cam shaft of the feeding machine, the final registering device comes to a sto when the feeder clutch is thrown out witn the result that a sheet at the prem gages upon the conveyor will not be registered and will be taken into the ress unless the. press is also stopped. For t l'lS reason it is sometimes desirable to "ear the shaft 117 to the driving train of tie feeder outside of the feeder clutch, or to the press, so as to insure the final registry of a sheet which reaches the press gages after the feeder is stopped.

155 is the vertical registering face or gage formed upon the plate 106 parallel with the direction of travel of the sheets. A yoke or collar 175 is ad'ustahly secured to the bar 80 and forme with an upright ear or lug 176 through which projects an adust-mg screw 177 r dly connected with :1 lug 178 upon the ate 106. Thumb nuts 179 and 180 are t eaded upon the screw 177 upon opposlte sides of the ear or lug 176 fol-the purpose of adjusting to a nicety the registering device just described.

It will be understood that the yoke or collar 175 which is adjustahly clamped to the bar of the final re istering mechanism secures the registering d avice to its supporting bar, the registering device freely adjustable upon the bar of the conveyor. In positioning the registering device for a particular piece of work. the yoke or collar 175 is loosened and the whole device shifted upon the bar to a. proximately correct position, when the yo re or collar 175 is secured to the bar and by manipulating the thumb nuts 1'? 9 and 180, the gage face 155 of the registering device is :gcurately adjusted to the exact point desu Immediately after the registry of a sheet at the front gages of the press, it is desirable to cause the si e registering gage 155 to recede or move away from the registered sheet so as to avoid thgpossihility of injuring the sheet as it is pull off of the oonveyer frame by the cylinder grippers and also to avoid the wearing action upon the ga e. For this purpose the bar 80 of the fin registering mechanism is mounted to move mtermib tently transversely of the conveyer frame, its movement outwardr taking place immediately after the fina re try of a sheet, and inwardly just prior to t 1e final register ing action. To eflect these movements of the su porting bar 80, I have devised a reversib e operating mechanism which will now be described.

200 is a yoke clamped upon the bar 80 just outside of the conveyer frame. This yoke 200 is formed with U-shaped sockets or recesses 201 in its opposite ends.

Journalcd in a bracket 202 extending outwardly from a part of the conveyer frame is a short vex-tidal shaft 203 which carries upon its opposite end a. doul'lle-armed rocker lever 204 having vertical openings in its opposite ends.

5405 is a stud or belt which is removably secured in one of the openin s in the ends of the rocker lever 20%. This molt or stud 205 may he threaded into the opening in the rocker lever or it. may be secured by a nutproper being transversely or by a securing pin. An anti-friction roller 306 isfreely jbnrnuled upon the end of the bolt 0: stud 205 and is adapted to engage the lJ-shaped socket or recess 201 at either and of the yoke 200. The short vertical shaft 203 has secured to its lower end a rock arm 208 carrying in its free end an anti-friction roller 209 which operates in 5 engagement with a cam plate 210 mounted upon the longitudinally movable bar 21] which is supported in hearings 212 secured to the press frame 1. A spring (not shown) retains the bar 80 in its inner normal .sition, thereb holding the anti-friction roller 209 in worliiug engagement with the cam plate 210. The reciprocating bar 211 is operated by a pitman 213 extending back to the feeding machine and connected with a cam actuated lever which is not shown. This reciprocating bar 211 is the throw-out actuating bar for the Dexter automatic press feeder as now constructed, operating upon the principle set forth in Patent No. 772,705 granted to me October 18th, 1904. From this construction, it will be observed that the reciprocation of the bar 211 causes the side registering mechanism to be intermittently moved outwardly and inwardly upon the conveyor frame.

The feature of providing a removable connecting stud or bolt between the doublearmed rocker lever and the yoke of the reciproca'ting bar of the registerin mechanism is important as a simple an convenient means for operating the final register ing mechanism as a right hand or left hand registering device. When the registering mechanism is arranged at the right hand of the conveyor as shown in the drawings, the coupling stud or' bolt connects the rearwardly projecting arms of the yoke 200 and rocker lever 20%, whereas, in the case of operatin the final registering mechanism at the leg hand side of the conveyor, the coupling stud or bolt would connectthe for wardly projecting arms of the yoke 200 and rocker lever 20%, with the result that in either case the side registering gage will be moved away from the edge of the sheet immedi' ately after the sheet is registered, and will be moved into registering position just before the final registry of a sheet.

It will be understood that I may provide a final registering mechanism at both sides of the conveyer frame, or I may depend upon the removability of the registering mechanism which enables me to shift the final registering mechanism from one side of the conveyor to the other.

The 0 ration of the mechanism as a vwhole \vi 1 be clear from the above description with but few words of explanation. The sheets are fed from the automatic feeding machine by the drop roller delivery mechanism to the sheet conveyer which rapidly carries the successive sheets forwardly to the press gages. As each sheet.- moves forwardly upon the conveyer, the twisted tapes shift it laterally into engagement with the preliminary registering plate or blade 75, which has [weviously been accurately adjusted to insure the registry edge of the Sheet In be presented to the final registering meclmnislu within a small fraction of an inch of final registering position. Tunnediatel'y after the arrest of the sheet bv the press gages, the upper registering roller is lowered to press the sheet against the const-antly driven under roller with the result that the edge of the sheet engaged by the said coiiperating rapidly running rollers will be instantly shifted laterally until its registering edge engages the registering face or gage 155. This final 1' istering action is extremely rapid, not on y because of the short registering movement required, but also because of the rapid motion of the registering rollers. The rollers engage the sheet very close to the registering edge so that the danger of buckling the edge of the sheetbe tween the bight of the rollers and the registering gage is reduced to a minimum. Furthermore, the sheet is closely confined between the plate 85 and the guide fingers 134 and 13-5 of the vertically movable frame 130. Immediately after the final registry of the sheet, the rcss gages are raised and the cylinder grlppels take the sheet and draw it oil from the conveyor frame.

The main feature of importance in my present invent-ion is the provision of the two sheet registering mechanisms, one effecting an accurate preliminary positioning of the sheet while it is moving forwardly upon the conveyer frame, and the other imparting a slight final registering ll'lOYBlllP-llt to the sheet after it comes to rest- -m engagement with the press gages.

I am aware that it is not new to employ twisted conveyor tapes for imparting ll'lc side registering movement to 3- sheet. and I am also aware that it is not new to employ two cot'iperatiug rollers for registering the sheet, but so far as I am aware, it has never been proposed to provide a rapid and accurate sheet registering mechanism for printing presses comprising a preliminary sheet registering or positioning device acting upon the sheets while they are in motion, in combination with a final re istering device which comes into act'on ailer the preliminarily registered sheet has come to a state of rest at the press gag's.
